The spelling is jewellery in the UK.  There’s a nice wikipedia article on American and British English spelling differences.

When I was a kid growing up  in Brooklyn I liked the British u added to colour and labour. I found it aesthetically pleasing or something. I wrote colour on a spelling test which was marked wrong. Being a nerd I brought in a dictionary and pointed out to my teacher that it was an acceptable alternate spelling.
